Solid Software Development Work With Clear Communication Throughout

Rachel Nguyen / CEO | Sep 08, 2026

We were happy with the final result. The developers were knowledgeable and made a few suggestions that ended up saving us time and money. We dealt with the same core team throughout, so we did not have to keep re-explaining things. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time.

The result looks great and performs well, and our internal team found it easy to take over. We had to follow up a few times on smaller bug fixes after launch. If you need a team that communicates well and delivers, they are a good choice.

Project summary

Kumsal Agency was brought in to rebuild an internal order management system that had outgrown its original design. They also took care of integrations with a couple of third-party tools we already used. Overall it was a 6-month engagement.

Kumsal Agency Delivered a Quality Software Development Solution on Time

Lukas Weber / CTO | Aug 31, 2026

Honestly, this was one of the smoothest projects we have run with an outside team. Communication was consistent. We had a weekly call, a shared Slack channel and a project board we could check at any time. They took the time to understand our business before suggesting anything, which we appreciated after previous agencies jumped straight into building.

Feedback from our customers has been very positive so far. I would recommend Kumsal Agency to anyone looking for a dependable Software Development partner.

Project summary

We engaged Kumsal Agency to build a custom operations platform to replace the spreadsheets and email threads we were running the business on. Scope included discovery workshops, development in two-week sprints and a short support period after launch. The engagement ran for about 4 months.
